A remnan- PAC'KAG-E WBAPPING MA CHINE.

Application Maw 10,1916. Seria1No.)6,553.

To all whom it may concern Be it known that I, ARTHUR F. lVnnns. a citizen of the United States, residing at San Francisco, in the county of San Francisco, State of (,lalifornia, have invented a new and useful Packagc-ivrapping Ma-' chine, of which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a package wrapping machine and its object is to produce a machine which will be simple and easily operated, and which will wrap a parcel and seal"the'"wrapper on the ends thereof in a.

single operation. the packages being discharged from the machine ready to be packed into boxes for shipment.

An object of the invention is to provide means whereby the paper to be wrapped around the parcels may be more certainly directed into the position it is to occupy just prior to the time the package is pushed against the same. a suitable receiving table advancing each time a fresh sheet is to be placed in position.

Another object of the invention is to provide means whereby the packages may be' sealed as they are discharged from the machine.

Another. object of the invention is to provide means whereby the machine will be generally operated only when a package is placed therein, the major portion thereof being out of operation unless said package is passing through the machine in its travel.

()ther ob'ect s of the invention will a ear 1 pp tion of the discharge .eonveyer,

as the description proceeds.

An embodiment of the invention is shown in the drawing in which the same reference numeral is applied to the same portion throughout, but I am aware that there may be many modifications thereof,

The numerals 1 and 2 indicate rectangulai' frames forming the sides of the machine. These frames are suitably secured to two bases 3 and i, which bases serve to connect the side frames at the bottom and to support them at a convenient elevation above the floor. Rods 5, 6, 7 and 8 at the corners of the frames serve to hold them rigidly in the desired position parallel to one another and at such a distance apart as is necessary to permit the assemblage therein of the several working parts of the machine. Each of the frames is provided with a horizontal cross piece about midway the height of the frame as indicated at 9 and 10, saidrross ieces servin' to su' ort the hearinqs 11 12. 13, 14, 15 and 16.

The bearings just mentioned support three parallel horizontal shafts l7, l8 and 19 which are the main driving shafts of the machine. These shafts are connected together and are driven in unison by means of three gears 20, 21 and The center shaft 18 also has a gear 23 thereon which is in mesh with a smaller gear 24 on a shaft which shaft also has a larger gear 26 thereon .'the larger gear being in mesh with a small gear 27 on the shaft 28, the latter shaft also carrying a pulley 29 around which the belt 30 from the motor pulley 31 extends.

The result of the construction just out lined is that the shaft 18 as well as the shaftsl? and 19 which are connected there-' ing a hook 84 pivoted to one of the spokesof the gear 21 at 35 for the purpose of driving the gear 21 when necessary. The opposite end of the hook is pivoted to a lever 36 which has a curved portion 37 which engages a plate 88 when it is desired to operate the machine, as will be later explained. The Wheel 21 carries a spring 39 which normall holds the lever 36 in a position for the hoo 34 to engage the roller 33, but as said lever is carried around its heel piece will contact with the plate 38 which will lift the hook so the roller cannot engage it. As soon as the parcel has been placed in position on the trip .262, the plate 38 will be pushed out so the roller can engage the hook on its next revolution. The machine is at rest except when the trip 262 has been operated.

At the top of the frames there is a plate 40 whichserves to connect the frames together and to form a sort of support for the carton feeding plunger 41 as well as a support for the legs 42, 43, 42 and 43' carrying the work table 44. Supported on the cross bars 45' and 46' is the plate 40 from which cross bars depend four bolts 45. 46.

47 and 48, which bolts carry cross bars l7 and 48 and a horizontally extending chute 49, said chute also being supported at the front end by means of two brackets 50, 51 connected with four brackets 52, 53, 54 and The brackets just mentioned have suitable bearings 53 and 55 at their outer ends for a shaft 56 while at the other end of the chute 49 there are two downwardly depending arms 58, 59 which have a shaft 60 journaled at their lower ends.

The shafts 56 and 60 are each provided with two sprocket gears as indicated at (51,

6'2. (33 and 64, over which gears sprocket chains and 66 pass, said sprocket chains carrying suitable flights 07 for the discharge from the machine of the folded package. In. order to prevent the flights from dropping down on the other parts of the man chine the chute 49 has six depending links 67. 68, 69, 7O, 71 and 72 which support two rails 73, 74 for the flights of the chains to ride back on, and in order to hold the flights in an upright position as they pass through the chute each flight is provided with two tail-pieces as indicatcdsat 75 to slide on the chute bottom 76, which latter is supported by three bars 76, 76 and 76.

Just in front of the pl ungcr 41 there are two, angular posts 77. 78 which supper! a transverse partition 79. which forms the registering device for placing the packages in the machine. A pair of guides 80, 81 are connected to the posts 77, 78 in order to guide the plunger 41. Just in back of the transverse partition 79 there is a chute hav; ing partitions 82 and 83 through which the paper sheet 84 passes after it leaves the feed roll 85. The feed roll 85 and paper supply roll 86 are supported on suitable standards 87, 88, 89 and 90, which standards are in turn supported on two frames 91, 92 resting on the to of the sides frames 1 and 2 near one end t iereof.

The paper feed roll 85 is journaled on a shaft 93 and has a pinion 94 thereon which is in mesh with a vertically movable rack bar 95. The rack bar 95 is held in engage ment with the pinion 94 by means of a roller 96 journaled on a pin 97 carried by a bracket '98, which bracket is supported on the jourtion and then only enough to deliver paper for one wrapper. In order to insure the feed roll having a good tractive effort it is provided with a friction surface 101 and a small roller 102 supported by links 103, 104 bears on the paper sheet as it passes over the feed roller to hold the sheet in'contact therewith, so that the proper amount of paper will be fed down into the chute formed by the plates '82, 83 whenever a parcel is to be wrapped, and springs 105, 106 hold the roller 102 down"tightly as may be required.

In back of the paper supply roll 86 there are two pivoted arms 107, 108 carrying a plate 109, which plate is held normally in contact with the paper on the paper supply roll by means of springs 110 and 110, the

objectbeing to prevent the paper supply \Vhen it roll front unrolhng'too rapidly.

is desired to disengage the brake from thepaper supply roll a hook 112 pivoted on therewith at the proper time.

top of the support 113 is engaged with a pin on the arm 107, thereby preventing the plate 107 from coming on the paper roll.

The frames 91. 92 are provided with guide ways as indicated at 114, 115, said guide.

ways providing a support and path of travel for the knife 116, which knife projects through slots in the plates 82, 83 at 117 when the paper strip is to be cut off.

The horizontal support 118 which carries the journal posts 89, 90 has depending therefrom an L shaped bracket 119 which has a slot for a rearwardly extending bar 120, which bar is for the purpose of moving the knife forward when the lever 121 contacts A lug 122 is secured to the knife and depends therefrom'and carries a roller 123 which contacts with a spring 124. An auxiliary spiral spring 124' assiststhe spring 124 in pushing the knife back after the paper has been cut.

Situated below the knife is the parcel carrier, said parcel carrier comprisinga horizontal bottom 125 connected with a horizontal top piece 126 by means of two vertical side pieces 127. 128, these four parts forming a horizontally extending open ended chute into which the. parcel to be wrapped is pushedi The parcel carrier is provided I endsby a bar 131 against which the parcel to be wrapped is pushed when it is pushed into the parcel carrier. The package carin' contact with the paper rier slides vertically on two guide bars 131. 131", guides 132, 132 being secured to the carrier sides.

The bars 132,133 are connected to a rearwardly extending bar 134. At the back end the bar 134 is provided with a depending lug 135, a small stiff spring 136 depending form a guide way for the bar 134.

The plates-130, 130 carry depending pins 140, 141 which project through slots in the plate 125 and afford means whereby said plates are guided in their travel in addition to the guiding means afl'orded by the plates 137, 138. The plates 130, 130 are also provided with pivoted levers 142, 143, the heels of which strike the pins 141, 140 while the longer ends thereof strike a pin 144 projecting upwardly from the bottom plate 125. Springs 145. 146 connect the levers 142. 143 with the plates 130', 130 in order to draw the plate 131 against which the parcel pushed back into the parcel carrier when the parcel has been pushed therefrom into the discharge chute. It will beobserved that the plate 131 moves ofl" the plate 125 to the right Fig. 9 not less than the width of the carton, and as the pin 144 is fixed in position said levers 142 and 143 and springs 145, 146 will return the plate and attached parts as soon as they are released. i

At the sides of the bars 130, 130 are two upwardly projecting corner angles 150. 151 which are secured to the bottom plate 125 and which hold the end folding plates 152.

153 in their proper position. The end folding plates 153, 152 have inclined ends as illustrated at 154. 155 for the purpose of forming one of the folds of the paper on the parcel and they are connected together at their back ends by means of a U shaped plate 156 which is in turn connected to a rearwardly connecting bar 157, said bar 5 having a pin 158 projecting therefrom which extends into a slot formed by two 'bars 159. 160 to act as a guide.

The bars 159. 160 are supported by two cross bars 161. 162, the bar 161 being so po- V sitioned that the pin 158 is moved Depending from the pet two lugs 11 2, 173, which lugs are connected by s. shut't 1H and which shaft supports four arms 175, 176, 177 and 178, said arms being rigidly secured thereto and to each other. Springs 179, 180 beer on the'nnderside of the package carrier and on, top the arms 175 and 178 to hold them normally down. At the front of the package carrier there are two depending guide members 181, 182 which carry slide bars 183, 18%, said bars being fastened respectively to the arms 175 and 178.

The upright. portions of the frames 1 and and just out of contact with the largest operating cam carry a cross bar 185, which cross bar supports a stop 186 which the two arms 1" 177 contact with when the packto, carrier descends for the purpose-of making the bottom fold on the package. 7

The package carrier is supported by two links 186, 187 connected at their lower ends to levers 188, 189 on a transverse strait 1%. arms 2191, S2 cerrring balance weights 193. 194 to assist in raising the carriage. springs 195, 196 being also used for the some purpose. The shaft 190 also provided with on arin 197 rigidly connected therewith which has a roller 198. said roller being ongaged by a large cane 199 on the shaft 17.

Pivoted on a bar .200 at the bottom of the fences 1 and is a long lever 201 which is held normally in the position shown in Fig. 9 by means of the spring This lever extends up for enough to contact with the end of the bar 120 which operates the knife, and it is provided with e pir which contacts with the heel piece 1-35 of the car 134 when the parcel is to be pushed out of: the package carrier.

The shaft 17 carries three cams 199, 205 and 206. The com 199 operates the lever 197, Which lever depresses the package carrier often the package has been pushed thereinto and allows it to be raised with the force supplied thereto by the springs counterbeloncos. The com 205 operates on n roller 207 carried by an arm 208 rigidly connected with the long lever 201. The cam 206 operates on. e roller 209 carried by a lever 210 pivoted at the opposite to a bar 211. supported by the side frames and 2. The bar 210 is held normally in the position shown in Fig. 9 by means of the long spiral spring 212. The car 210 strikes a stop screw 210 on its up strike which is carried by a bar 210?.

Pivotally mounted on the shlift 6O supporting the sprocket Wheel 61 is a lever 213, (See Figs. 7 and 9) the lower end. of which has a projecting portion 214 in contact with a roller 215 on the lever 210. A spiral spring 216 at the upper end of the lever 213 holds it normally against the roller and it carries a rod 21'? which engages de pending lugs "218 on the paper receiving table 215). 'l. he paper receiving table rests on a partition 2 0 at the receiving end of the dischnr e chute and is carried by two guide rails 221 and 222. The table 219 moves forward when the paper is about to be fed thereon to prevent the paper from passing down into the space prcviouslv occupied by the box carriage. The rails 221., 222 are supported at one end by suitable brackets on the top of the partition 220 and at their other end they are supported by legs 223, 22% which rest on the top of the discharge chute. T he rails 221, 222 are provided with overlapping; arms 225 which bear on the plate 219 and hold it in the proper position as it. is operated by the lever 213.

The shaft 19 is provided With a. com 227 which beers on a. roller on the upper end of a. lever pivoted at the bottom or the machine one on :1 bar 230, which her also carries levers 231, 231 connected to short llIllIS 232 end 282 at its upper end, said links being pivotally connected with the package feeding plunger 41. posi ion of the. plunger ll is determined by means or :1 sc screw 233 carried by the lever 229 and which bears on e bar 234; connected with the levers 231, 231'. Then plunger all is retracted by means of stifi springs 256, 256 which are connected with the side frames 1 and 2 and with the levers 231, 23.

The lever 21 is connected with the reel; her for the purpose of operating the paper teed roll each time a package is forced into tire package carrier.

The disclri chute 49 has two plates 235, connected thereto at its inlet end. These plates are flaring on the receiving end and have their upper corners curved to permit the upper unfolded flap of the paper to pass thereover until said. flaps come into contact with the side of the chute just outside these two plates, whereupon the final told is produced, the upper flaps being bent down over the ends of the parcel.

Since the parcels are ordinarily wrapped with wax paper of some kind it is possible to seal them with heat and dot electric heaters 238, ends of the parcel and also seal the top fold as they pass through the discharge chute. The shaft 56 at the end of the discharge chntc'is provided with e sprocket Wheel 250 over which 1 chain 253. passes and in order to depress the chain below some of the other parts of the machine a sprocket wheel 252 is provided, und 2: which theupper run of the chain passes. Since the chain must be driven in the direction of the arrow, Fig. 4, it is necessary to drive it from the center shaft. 18, that shaft being provided with e spro'dset wheel for that purpose. The shaft 19 is provided with a sprocket wheel 254 which is The precise 239, 240 are provided which seal the loosely mounted thereon and under which the lower chain 251 passes, the object being to prevent the chain from dragging on the underside of the shaft 19.

5' Since it is desired to feed the paper through the machine and to operate the plunger only when a parcel is in position to e fed thereinto, the spring 39 and pivoted hook 3a are so arranged that when the heel piece '37 of the lever 36 strikes the plate 38 the hook will be lifted so that it: will not be engaged by the roller 33, but as soon as the plate 38 is pushed out of engagement with the, heel piece 37 the spring 39 pushes the book down low enough so'.' that the plate 38 will engage the same and cause the wheels to make one revolution, andif a parcel has been placed in the feeding position it will continue to run. The plate 38.is pivoted on a longitudinally extending bar 257 and it has a small weight 258 which tends to hold it in position to engage the heel piece 37 whenever a parcel is not placed in the feed ing position. v

The plate 38'is connected to a link 259, which link is connected to a lever 260, said lever being pivoted at its center on a bracket 260 and connected at its upper end to a bell crank lever '261 on the portion 262 which projects above the feed table on which parcels are placed ready for feeding. It is sometimes necessary to operate the machine without having a parcel pass therethrough and in order to provide convenient means for this a lever 263 is provided which can be operated by hand to shift the plate out of the path of the heel piece 37 of the lever 36. This lever is pivoted on the frame of the machine at 264 and has a link 265 which con- 40 nects it with the plate 38.

The machine is driven from the motor 266 by means of a belt 30 and a switch 268 is provided for controlling the motor circuit, while a switch 259 is provided for controlling the heating circuit, suitable cables running from said switches to the heater and motor. On the front of the machine a resistance box 270 is provided to control the heat of the heaters to which tnev electric 5o cables run.

In Fig. 28 there is shown a diagrammatic view of the electric wiring in which the numerals 272, 273 indicate the inlet wires and 274 a main switch. From the switch 274 wires 275, 276, 277, 278, and 279 extend to the switch, resistance box and electric heaters. From the switch 269-wires 280, 281, 282, 283 extend to the switch 269, motor and return to the main switch 274.

The character of the folding operations is illustrated in Figs. 22 to 27 inclusive in which Fig. 26 indicates the completely folded package and Fig. 22- indicates the condition of the package when being first pushed into the package carrier. The numeral 284 indi cates the ackage,285 indicating the wrap per therefor. It will be observed that the wrapper when in position to be carried into 'the package carrier around the package lies on the paper table 319 and stands in front of the package so that when the package is pushed into the package carrier the paper is folded at two corners one short fold at the top of the package and a longer told at the bottom as indicated at 286 and 287 rcspectively. As soon as the fold shown in Fig. 22 has been made the package carrier begins to move down and as it does so the cam 186 forms the fold shown at 288, the fold at 289 having been started as soon as the package carrier begins to move down. As soon as the fold 288 has been made the cam 166 moves those folding plates out together thereby leaving space for the plates 183, 18% to come up and make the fold 290 at each end of the package and these plates remain in position until the package has been pushed into the discharge chute, the first movement of whichproduces the fold at 291 and a further movement of which produces the fold across the end at 292, the plates 235, 236 forming said fold 292, the only remaining fold then is the top fold 294 at each end of the package and this fold is produced by that portion of the wrapper which passes over the to of the plates 235, 236, the dischargechute sides 235, 236 turning said flaps down. The complete operation of the machine is as follows: With the motor running the 1. chain belts 65 and 66 run continuously and so long as no package is placed in the machine the hook 34.; will be lifted over the pin 33 each time the lever 37 comes to the plate 38 so that none of the feeding or other machine operations will take place. However, as soon as a package has been )laced in position between the chute sides Tl, 78 the package will bear on the trip lever 262 thereb moving the late 38 out so that the lever 3 will not strike it as it passes around, whereupon the pin 33 will carry the Wheel 21 around asthe other wheels will also be can ricd. Prior to this time the paper will have been placed by hand between the two partitions,;82, 83 and run down far enough to cover as package. This sheet will then be cut oil by the hand 'opcration of the knife 116, whereupon the machine is ready to proceed with its Work.

The first step will be for; the plunger 41 to puslfi the package into the package carrier against the plate 131 carrying the wrapper along with it. As soon as the parcel has been pushed into the package carrier the plunger 41 will be retracted and the lever 20.]. will begin to move forward as the package carrier begins to move down. While the package carrier is moving downv the cam 166 operating on the rod 164 will cause the two plates 154, 155 to form the first end fold by moving forwardly. As the package carrier moves to the bottom of its travel these two plates are retracted to their original position and the stop 186 causes the two plates 183, 15+ to move up and form the bottom fold and while the descent is being made the lever 210 will move down, thereby bringing the rod 95 down and moving' a .iresh length of paper into position. At the same time that the paper is being moved down the paper receiving table "219 is moved forwardly by the cam 21% passing over the top of the roller 215 and as soon the return stroke is made the receiving table for the paper will move back to the position shown in Fig. 9 with the length of paper thereon, While at. the bottom of its travel the package carrier will have the package therein pushed into the discharge chute by the pin 203 contacting with the depending lug 135 on the plate 134 and at this same time the lever .12]. will contact with the plate 120 cutting off the length of paperthat has just been fed down to the rece ving carriage. As soon as the paper has beencutand the parcel pushed out of the parcel carrier the lever 201 will be allowed to return to the position shown in Fig. 7

As the parcel is pushed into the discharge chute the nextto last told on its forward edge is produced by the plates contacting with the plates 235, 236, the upper edges of the wrapper passing over the top of said plates and being pushed downwardly by the outer edges of the discharge chute as indicated at 285 and 236, The parcel is pushed far enough into the discharge chute for the flight. bars 67 to contact therewith and push it on outv to a suitable receiving table at the end of the machine and as itis pushed through the machine it will pass the heaters which will cause the paraffin in the Wrapper to be heated sutiiciently to seal the several folds together.
